NlUCILAGEm-l--IOl- DERl SPECIFICATION forming part of Letters Patent No. 448,665, dated March 24,1891.

Application filed August 25, 1890. Serial No. 362,944. (No model.)

10 @ZZ whom, t may concern,.-

Be it known that I, lVILLIAM O. NELSON, a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Mucilage Brushes and Ilolders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and to use the same.

My invention relates to an improvement in mucilage brushes or holders, the object being to provide a device in the nature of a fountain-pen for holdingasupplyof mucilage and automatically feeding it through a brush or dauber of cloth, hair, or preferably of sponge.

A further object is to provide means for forcing more or less mucilage into the dauber and for withdrawing the mucilage from the latter when it is no longer required.

lVith these ends in view my invention consists in certain novel features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a longitudinal sectional view of the preferred form of construction. Fig. 2 is an enlarged detail of the stem. Fig. 3 is an enlarged sec tional view of the plug, and Fig. 4 is a view 3o of a modification, partly in section.

A represents the barrel or body of the device in which themucila-ge is contained. rThis barrel is preferably alittle tapered at one end and has a small opening through which the dauber, of hair, cloth, or usually of sponge, as shown in the drawings, is drawn Vto receive the mucilage and spread it onto the surface or article to be mucilaged. The other end may be opened to be replenished with mucilage, 4o after which it is closed by means of a suitable device for the purpose, now to be described. This consists, first, of a hollow plug, which for convenience and economy is preferably composed of two telescoping shells l and 2, fitted snugly together, as shown in Fig. 3, and the outer one being of a proper size to fit tightly in the open end of the barrel. The opening 3 of this plug tapers, as shown, and the opening 4 in the opposite end is screw- 5o threaded, the design of these openings being to receive the stem 5, which ordinarily works freely in the plug; but I may add in this connection that the stem is provided with an enlarged head G at one end, made in shape to correspond with opening 3 and adapted to lill 55 the latter when drawn back as far as possible, and a suitable distance back is furnished with screw-threads 7, adapted to screw into the hole 1t for the purpose of locking the stem and plug together when the parts are assembled, and the plug is inserted in the barrel after the barrel has been replenished to prevent forcing the mueilage out through the dauber at this time, as would otherwise result. This arrangement, however,is only temporary, and the locking of the plug and stem together 1s only intended to be resorted to when the plug is first inserted after replenishing the barrel with in ucilage.

A cap S is secured on the outer end of the stem, and this cap extends loosely over the open end of the barrel and is adapted to work back and forth thereon to force air into the barrel over or back of the mucilage to saturate the dauber or to withdraw air from the barrel to withdraw the mucilage from the dauber. i

A small spiral spring lO is placed on the stein between the cap andplug for the purpose of keeping the latter normally outward, and, while this spring is calculated to have Sufficient tensile strength to retain the cap in this position in case the device is dropped or 1n case it is rested on this end, yet the strength of the spring is not sufficient to force the cap outward when it has been pushed on as far as possible to force air into the barrel, and when the cap is pulled back it is done by hand and not by the spring. A cap 1l is placed over the dauber.

In the modification the plug is made in one piece, the spring is dispensed with, and no provision is made for locking the plug and stem together. Again, in this construction the outer end of the stem is screw-threaded, and after extending through a hole for it in the cap has a nut l2 screwed thereon.

It is evident that slight changes might bc resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to IOO the exaet Construction herein set l'orth; but,

Having fully deseribed my invention, what I elaini as new, and desire to secure by lietters Patent, is

1. The eolnbination, with a barrel having an opening in one end for the discharge of its contents, of a plug t'or closing the other end and a movable eap fitted to the end, said Gap having a stem which passes loosely through the plug, substantially as set forth.

L. 'lhe combination, with a barrel having an opening in one end with a dauber therein and a plug for closing the opposite end, ofa Cap fitted to this end, said Cap having a stem which extends loosel5v through the plug, and means for locking the plugand stem together temporarily, substaiitially as set forth.

3. The combination, with a barrel having a sponge in one end and open at the opposite end, of a plug Composed ot' teleseoping shells fitted in the open end, a eap loosely mounted on this end of the barrel, a stem secured to the eap and passing loosel) through theplug, a spring on the stein between the plug and Cap, and means for loeking the plug and stein together, substantially as set forth.

l. The eombination, with a barrel having an opening in eaeh end, of a plug for closing One end and a movable eap having eonneetion with the plug and fitted to the tube and adapted to increase and decrease the air space in the barrel by being slid baek and forth, substantially as set forth.

ln testimony whereof I have signed this Specification in the )resenee of two subscribing witnesses.

WUAM O. NELSON.
